如何在python中的字符串后打印数字总和？

Question

我想在python的同一行中的字符串之后打印数字的总和。

print("Your answer is correct, this is your score:" + score=score+1)

Answer 1

您可以使用 f 字符串，但您还应该在打印之前设置score的值，以便更清楚发生了什么：

score += 1
print(f"Your answer is correct, this is your score: {score}")

您可以按照自己的方式进行操作，但必须先将score转换为字符串，然后才能将其（通过+ ）连接到另一个字符串：

score += 1
print("Your answer is correct, this is your score: " + str(score))

另一种方法是将score作为参数添加到print ； 在这种情况下，您不必将其转换为字符串：

score += 1
print("Your answer is correct, this is your score: ", score)

Answer 2

打印前将分数加 1。

您还需要将分数转换为字符串，然后才能连接它。 或者您可以使用字符串格式，这更简单。

score += 1
print(f"Your answer is correct, this is your score: {score}"

Answer 3

如果使用 f 字符串，则可以在格式中添加操作：

print(f"Your answer is correct, this is your score: {score+1}")

Answer 4

有几种方法

>>> score = 10 #you do your calculation first
>>> print("Your answer is correct, this is your score:", score)#print can take any number of arguments
Your answer is correct, this is your score: 10
>>> print("Your answer is correct, this is your score: " + str(score))#make it a string first and concatenate it
Your answer is correct, this is your score: 10
>>> print(f"Your answer is correct, this is your score: {score}")#use f-string
Your answer is correct, this is your score: 10
>>> 

也有 2 或 3 种其他方法来制作字符串，但我推荐第一个和第三个示例，特别是 f-string，它们很棒。

此外，在 python 3.8 中，他们引入了赋值表达式:= ，因此您也可以像最初尝试的那样进行操作，只需进行一些调整...

>>> score=10 
>>> print("Your answer is correct, this is your score:", (score:=score+1))
Your answer is correct, this is your score: 11
>>> score
11
>>>
